Abstract

A method for cementing a casing (4) in a wellbore, the method having the following steps: attaching a valve (1) to a casing; locking the valve in an open configuration; running the casing and the valve into the wellbore;
reverse circulating a cement composition (22) down an annulus defined between the casing and the wellbore; injecting a plurality of plugs (20) into the annulus; unlocking the valve with the plurality of plugs; and closing the valve.

Claims (19)

1. A method of cementing a casing in a wellbore, comprising:
attaching a valve to the casing;
locking the valve in an open configuration;
running the casing and the valve into the wellbore;
reverse circulating a cement composition down an annulus defined between the casing and the wellbore;
injecting a plurality of plugs into the annulus;
unlocking the valve with the plurality of plugs; and closing the valve.
2. The method of claim 1 wherein attaching the valve to the casing comprises making a flapper valve up to the casing.
3. The method of claim 1 wherein attaching the valve to the casing comprises making a poppet valve up to the casing.
4. The method of claim 1 wherein locking the valve in an open configuration comprises stinging a pin into the valve.
5. The method of claim 1 wherein injecting the plurality of plugs into the annulus comprises injecting the plugs at a leading edge of the cement composition.
6. The method of claim 1 wherein unlocking the valve with the plurality of plugs comprises trapping at least a portion of the plugs in a strainer connected to a pin stung into the valve, wherein the trapped portion of the plugs restricts fluid flow through the strainer.
7. The method of claim 1 wherein closing the valve comprises biasing the valve to a closed position, whereby the valve closes upon being unlocked.
8. A valve comprising:
a valve housing defining a valve seat;
a closure element adjustably connected to the valve housing, wherein the closure element is configurable relative to the valve seat in open and closed configurations;
a lock in mechanical communication with the closure element to lock the closure element in the open configuration when the lock is assembled in the valve housing, wherein the lock comprises a strainer; and a bias element in mechanical communication with the valve housing and the closure element, wherein the bias element biases the closure element to the closed configuration.
9. The valve of claim 8 wherein the closure element comprises a flapper.
10. The valve of claim 8 wherein the closure element comprises a poppet.
11. The valve of claim 8 wherein the lock comprise a stinger that stings into the valve seat when the lock is assembled in the valve housing.
12. The valve of claim 8 wherein the bias element comprises a spring.
13. A system for reverse-circulation cementing a casing in a wellbore, comprising:
a valve housing defining a valve seat;
a closure element adjustably connected to the valve housing, wherein the closure element is configurable relative to the valve seat in open and closed configurations;
a lock in mechanical communication with the closure element to lock the closure element in the open configuration when the lock is assembled in the valve housing, wherein the lock comprises a strainer with holes having a hole dimension;
a bias element in mechanical communication with the valve housing and the closure element, wherein the bias element biases the closure element to the closed configuration; and a plurality of plugs, wherein the plugs have a plug dimension larger than the hole dimension.
14. The system of claim 13 wherein the closure element comprises a flapper.
15. The system of claim 13 wherein the closure element comprises a poppet.
16. The system of claim 13 wherein the lock comprise a stinger that stings into the valve seat when the lock is assembled in the valve housing.
17. The system of claim 13 wherein the bias element comprises a spring.
18. The system of claim 13 wherein the plurality of plugs comprises spheres.
19. The system of claim 13 wherein the plurality of plugs comprises spheres having an outside diameter between about 0.30 inches to about 0.45 inches.
